ABSTRACT
C inside the oven. Note that the oven is not tightly sealed.
Problem 1.3:
Consider an automobile engine with a gas tank volume of 20 gal (1 gal
=
3.785 l). Instead of gasoline, we wish to use natural gas (methane) as a fuel for the automobile. The natural gas enters the adiabatic tank from a pressurized gas line at 300 K and the charging process stops once the pressure reaches 50 bar. Determine the mass of gas that can be accommodated. Treat the gas as ideal. Make reasonable assumptions. c
=
36 kJ/kmol K,
=
8.314 kJ/kmol.R
Problem 1.4:
Consider the human body, which is an open system. The body loses heat at the rate of 0.110 kW at constant temperature. The mass flow rates in and out of the nose are assumed to be equal and is given as 6 g/min.
